The invention relates toiapparatus for heatj ingV water for various purposes.

The principal object of the invention, generally stated, is to provide a water `heater` -adapted to beused in combination with Aa pump, engine or, infact, any otherdeviceor apparatus employing steam as motive power, heating means or in any other capacity, the heater of the present inventionbeing so constiucted and arranged as tovutilize the eX- liaust steam from any of such devices;

The object of the inventiominore specifically stated, is to provide a water heater in conjunction with any 'steam operated mecha l nism and soconstructed and arrangedthat the exhaust steam from such is employed Y eitheralone or togetherv with live steam or the purpose of raising the temperature of waterto a desired degreeyfthe device econoy mizing greatly in that the heat usually wasted in the 'exhaust steam is utilized. f

Another object of the invention is to pro- Y vide a water heater having anautomatically acting back pressure valve which willoper-v A ate to relieve any excess steam pressure gen- Y erated in the heater or fed thereto in the form Y,of exhaustfrom the mechanism inV conjuncn f1 Y tion with which the device is-employed.v

Afurther object ofthe invention is to provide a water heater so constructed4 and Varranged as toproduce'a continuous' v heating action on wateriwhich'may beme're or less constantly flowing, it being permissible that theheatedrwater be drawn from the device or by' means ofV a pump or the like.

' Another object i vide a w'aterheater ofvthis character which, 0` if used-in combination 'fwith asteam pump, j Vwill .act to heatwater andemaintain it at' a substantially constant temperaturepractically regardlessof thedemands upon Vit'vinasmuch as the heatingeiect is dependent upon f V the exhaust from `the pump which, in turn,

depends upon the speed of thepump as determined by the steam-f pressure supplied thereto, there being consequently a coordination of action, it being a featurel that the '50 pump may be equipped with' a governor set or exhaust steam in proper proportions, or either alone,is discharged, practically all portions of the water being'acted upon almostin- Vthe requirements of the plant `in .heater isembodied.

` In the'operationof the device, it is firstn necessary to' openl the control' valve 6V in' the` water supply line sothat -the system may be filled with water tothe desired level. Ow-

ing to the*y fact that the'tank 9 communicates with the pipe'or conduitl at vpoints aboveP and below the waterheating chamberv 3 it is" clear that tlie'level'ofthe water in the tank '9 Vwill be the same as in tliejheater and as water is drawn outrat anytime through the pipe-lvthe float 10 will operate to controltheT flowrofV water'so thatythe maintained lat all times. y 17 would be close'dand keptso until: the; water tempera; t valve may desired levelwill be be opened to Assumingy that thefsyste-m-has been prop- .,lerly lil-led ywithwyvatento start the heating?,

VThe point at which vthe safety valve opens may of coursebe ad- .justed and this detail depends uponvthe particular type of valve employed.- If Vit develops't-hat the Water is heated to too higlif a temperatureor if there isA a constant cape of steam throughthe safety valve, the' valve 26 may be closed and the-valve 25 throughthe pipe 23 Will no longer enter the heater but Will pass directlyto the discharge pipe '19 at a'point beyond the safety valve.v
